    BackgroundThe Geleijnse score, which was proposed to assess for coronary ischemia, has practical limitations.ObjectivesOur aim was to design and evaluate a simplified version of the Geleijnse score.MethodsWe enrolled patients with suspected coronary heart disease but negative troponin T or absence of enzymatic curve, and a non-diagnostic 12-lead ECG. The initial study was performed in a retrospective derivation cohort and the results were subsequently validated in a prospective cohort.ResultsFrom 109 patients included in the derivation cohort, 33 (30.3%) received a diagnosis of coronary heart disease. Chest pain with both arms radiation (OR 3.54), severe intensity (OR 2.41), improvement by nitroglycerin (OR 1.61), associated dyspnea (OR 1.97) and prior exertional angina history (OR 2.91) were independently associated with an ischemic origin on multivariate logistic regression analysis. ROC curves comparison demonstrated both the original and simplified scores presented modest predictive ability with significant difference when analyzed using dichotomous cut-offs (0.647 [simplified] vs. 0.544 [original], p聽=聽0.042) but not as a continuous variable (0.670 [simplified] vs. 0.621 [original], p聽=聽0.396). In 305 patients from the validation cohort, the simplified score presented extensively increased predictive accuracy than the Geleijnse, in the continuous (c-indexes聽=聽0.735聽vs. 0.685, p聽=聽0.040) and the dichotomic (c-indexes聽=聽0.682聽vs. 0.514, pConclusionsA simplified version of the Geleijnse score, including some routine clinical manifestations associated with coronary heart disease, presented significantly better predictive ability compared to the original score

    INTRODUCCI脫N. El dolor tor谩cico (DT) agudo es actualmente la segunda causa de consulta en los servicios de urgencias. Discriminar el origen del DT es uno de los grandes retos en la asistencia de estos servicios, debido a las m煤ltiples causas que pueden originarlo. Entre el 2 y el 4% de los pacientes que son dados de alta desde los servicios de urgencias de manera inadecuada, presentan un infarto agudo de miocardio. Hip贸tesis: A pesar de la dificultad para diferenciar si el origen del DT es coronario o no, debido a las numerosas similitudes en la presentaci贸n cl铆nica del dolor, planteamos la hip贸tesis de que pueden haber diferencias, en cuanto a la presentaci贸n cl铆nica, entre el paciente que est谩 sufriendo un S铆ndrome Coronario Agudo (SCA) y el que no lo presenta. Objetivos: 1. Determinar las caracter铆sticas cl铆nicas y del DT de los pacientes ingresados por dolor tor谩cico, as铆 como compararlas a pacientes con diagn贸stico inicial de SCA. 2. Analizar la asociaci贸n de estas variables, tanto cl铆nicas como del DT, en el diagn贸stico final de enfermedad coronaria. Evaluar el poder diagn贸stico de la conocida escala de Geleijnse en la poblaci贸n analizada. 3. Construir una nueva escala simplificada para el diagn贸stico de enfermedad coronaria en la poblaci贸n estudiada. 4. Comparaci贸n la potencia diagnostica de la nueva escala frente a la establecida de Geleijnse en cuanto a enfermedad coronaria en la poblaci贸n estudiada. 5. Evaluar el valor pron贸stico de la escala a corto-medio plazo y comparaci贸n con principales escalas de estratificaci贸n de riesgo. M脡TODOS. Estudio observacional prospectivo, con una parte transversal y otra longitudinal de pacientes que acudieron al servicio de urgencias del Hospital Cl铆nico Universitario Virgen de la Arrixaca de Murcia, consultando por DT. Los pacientes se reclutaron entre junio del 2011 hasta noviembre del 2015. RESULTADOS Conclusi贸n 1: Los pacientes que consultan en el servicio de urgencia por DT y no muestran cambios sugestivos de isquemia ni en el electrocardiograma, ni en la evaluaci贸n de la troponina (Tn), no est谩n exentos de riesgo coronario, por lo que se hace imprescindible implementar estrategias que estimen el riesgo de SCA con mayor precisi贸n. Conclusi贸n 2: Las principales variables predictoras halladas en nuestra poblaci贸n son la edad mayor o igual de 67 a帽os, el sexo masculino, la dislipemia, los antecedentes de angina inestable y los antecedentes psiqui谩tricos. Respecto al DT, la irradiaci贸n a ambos brazos, el car谩cter fuertemente opresivo, la disnea y la presencia de angina de esfuerzos previa, mostraron ser variables predictoras independientes de SCA. Conclusi贸n 3: El an谩lisis de las principales variables predictoras halladas nos ha permitido construir la escala UDT-67, atribuyendo la puntuaci贸n a cada 铆tem en funci贸n de su valor predictivo. Esta escala simplifica considerablemente los 铆tems a valorar respecto al DT. Conclusi贸n 4: La escala UDT-67 es m谩s precisa que la escala del DT de Geleijnse et al. en la predicci贸n del origen coronario del dolor, en pacientes que consultaron por DT y en ausencia de cambios en el ECG sugestivos de isquemia o elevaci贸n plasm谩tica de Tn. La escala UDT-67 se puede aplicar de manera r谩pida y simple suponiendo una mejora en la exactitud diagn贸stica y pron贸stica sobre el esquema habitual. Conclusi贸n 5: El uso de la escala UDT-67 para predecir eventos adversos a los doce meses es baja. INTRODUCTION Acute chest pain is actually the second cause of consulting at emergency departments. Discriminating the origin of chest pain is one of the major challenges in the assistance of these services, because of can be caused by many factors. Between 2% and 4% of the patients who are discharged from the hospital inadequately, present Acute Coronary Syndrome (ACS). Hypothesis Despite the difficulty of differentiating if the chest pain origin is coronary or not, because many similarities in the clinical pain presentation, we contemplate the hypothesis there may be differences, in terms of clinical presentation, between the patient who is suffering a coronary disease and who is not. Objectives 1. Establishing clinical features and thoracic pain of hospitalized patients with thoracic pain, as well as to compare with patients with ACS initial diagnostic. 2. Analysing the association of these variables, just as clinical as chest pain, in the final diagnosis of the coronary disease. Evaluating the Geleijnse et al. score diagnosis power in the analysed population 3. Build a new simplified score to diagnosis coronary disease in our study population. 4. Comparison of the new score potency diagnosis as compared to the established Geleijnse et al. score in respect of coronary disease in the studied population. 5. Evaluating the prognosis value from the score in the short to medium term and compared with the major stratification risk scores. METHODS Prospective observational study, with a transversal and longitudinal part from patients who went to the Hospital Clinico Universitario Virgen de la Arrixaca de Murcia emergency department, presenting with chest pain. RESULTS Conclusion 1: Patients who visit the emergency department for typical chest pain and do not show changes suggestive of ischemia neither on the electrocardiogram nor on the evaluation of troponin are not free of coronary risk, so it is essential to implement strategies that estimate the risk of ACS more accurately. Conclusion 2: The main predictor variables encountered in our population aged greater than or equal to 67 years, male, dyslipidemia, history of unstable angina and psychiatric history. Regarding chest pain, irradiation to both arms, strongly pressing character, dyspnea and history of exertional angina, showed to be ACS independent predictor variables. Conclusion 3: The analysis of the major predictor variables found, allowed us to construct the UDT-67 score, assigning the score to each item according to its predictive value. This score greatly simplifies the items to be assessed for chest pain. Conclusion 4: The UDT-67 score is more accurate than Geleijnse et al. chest pain score predicting ACS, in patients who consulted for typical chest pain and no ECG changes or Troponin elevation. The UDT-67 score can be applied quickly and simply assuming an improvement in diagnostic and prognostic accuracy over the usual scheme. Conclusion 5: The predictive capacity and predictive utility of the UDT-67 score to predict adverse events at one year is mild
